The Fort Bend County Sheriff's Office shared an image of the road buckling near the Bellaire exit on Tuesday.
The incident closed the southbound exit along the Grand Parkway down to one lane.
Engineers with Fort Bend told ABC13 Wednesday morning they had poured concrete over it and hoped to have it cured before reopening. In an afternoon update, the sheriff's office said the roadway has been reopened.
It's unclear at this point what may have led to the road buckling.
